Abstract
This study aims to evaluate local forage's potential and nutritional content in the Payo agro-tourism area of Solok, West Sumatra, Indonesia, to be used as a ruminant feed. This study used a survey method by taking a sample of the forage that grows a lot in the area and then analyzed its nutritional content. The nutritional content analyzed were dry matter, ash, crude protein, crude fiber, crude fat, calcium, and phosphorus minerals. At the same time, the TDN value and the extracted material without nitrogen were calculated based on the formula. The results showed that 12 types of forage have the potential as ruminant feed, namely Panicum maximum, Tithonia diversifolia, Gliricidia sepium, Digitaria sp, Centrocema pubescens, Calliandra calothyrsus, Stachytarpheta jamaicensis, Bidens pilosa, Ipomea triloba, Micania Scandens, Asystasia gangetica, and corn straw. This study shows that Calliandra calothyrsus has the highest crude protein content, and Corn straw contains the lowest crude protein. The highest and lowest TDN values were Gliricidia sepium and Panicum maximum, respectively. Through the linear programming program, these 12 plants can be formulated into 4 ration formulations with 58% TDN and 15-16% crude protein.
